3 Claims.

My invention relates to atomizers and refers particularly to atomizersof such compactness4 and construction as will allow of their 'being.conveniently carried upon the person or in pocket-= books or hand bags.

Atomizers of the character described should .be absolutely free fromleakage, easily and effectively operated, free from stoppageof theseveral tubes essential in such constructions., non- D corrosive,readily relled and positive in action.

All of the above, and other valuable, attributes are possessed by thedevice of my application, as will be evident upon a consideration of myspecication and its accompanying drawings. In. the accompanying drawingsillustrating modied forms of the device of my invention,

similar parts are designated by similar numerals.'-

The particular form of the device oi my invention, shown in theaccompanying drawings comprises a casing 10 having a bottom 11 and 0open at the top. The bottom 11 has an open ing 12 and a threaded.v faceopening 13. 4A receptacle holder 14, carrying the removable receptacle15, has a lower threaded portion 16 capable of meshment with the threadsoi' the opening 13 and an extended annular flange 17 having an elongatedrecess 18 therein. finannular wall 19 forms a-cylindrical piston chamber20 which is closed at the bottom and open at the top. To maintain thewall 19 in upright posii0 tion, it has an extendedy portion 63 fittinginto a recess in the cover 22.

Within the chamber 20 and longitudinally movable therein is` a pistonrod 21, extending through an opening in the casing cover 22 and i5carrying a piston head 23 to which isI attached a leather washer 24. Aconical spiral spring 25 is positioned above the piston head 23 andattached thereto by being passed through the members 26, 26 carried bythe piston 23. The means 0 of attachment of the other end of the spring25 will be described later. The rod 21 carries a ing 10 surrounding 4thechamber 20 is cutaway for purposes described later. A tube 29 opens intothe lower portion of the chamber 20 and extends upwardly of the devicethrough an opening inthe cover 22 and thence upwardly' and angularlyoutwardly of the member 30, which is attached to the cover 22,terminating in an end 31 in which the opening of the tube is restricted.

The cover 22 carries the downwardly extended `annular iiange 32 havingan annular recess 33 therein, into which the upper portion of thereceptacle 15 fits, forming a hermetical seal withthe yieldable material34 when the cover is in closed position. A conical spiral spring 35forces the receptacle wall within the recess 33 and against the sealingmaterial 34. A tube 36 carrying a stop collar 37 is threaded within anopen ing-of the cover 22 and terminates in the tip 38 in which theopening is restricted. A wire strainer covers the lower opening of thetube 36, a lid', a closure member, 39 is pivoted at 40 to the member 36and has a recess, or chamber 41. The upper face of the member 36 has anextended portion 42 and av nat spring 43 having the extended portion 44is attached to the inner Vface of the closure 39 by means of rivets 45,45. A yieldable material 46 is carried within a recess of the closure 39and is so positioned that it abuts upon, and closes, the opening in thetip, or nozzle, 38 when the closure is in closed position thuscompletely closing the orifice of the tube 36.

The closure 39 carries also a bended wire member 47 which fits aroundthe nozzle 38 when the closure is closed, thus assisting in retainingthe closure in closed position. It will be noted that the spring 43 willtend to retain the closure 39 in open position, as shown in Figure 3 andwill tend to retain the closure in closed position as shown in Figure 6.

A tube 48 passes through the member 32, thus admitting air into thereceptacle 15.

Pivotally attached at 49, to the under face of .the cover 22 is anoperating member 50, having the recess 51, the arm 52 which is. bent tothe arm 53 carrying a closure plug 54, and an extended arm 55. ,Aresilient member, or spring, 56 is carried by the pivot 49 and the arm52 of the member 50, the resiliency of which tends to retain the member50 in the position shown in full lines in Figure '7. When the member 50is in its normal position, the closure plug 54 abuts upon and closes thetube 48, and the edge of the recess 51 enters the annular recess 56 oi'the piston rod 21, thus maintaining it Within the chamber 20.

The upper end of the spring 25 is inserted head 27. A portion 28 of theupper edge of cas hole in its lower position, into which the screw 59 iscapable of being threaded.

When the device is in closed position, the material 46 closes the nozzle38 and .the closure plug 54 closes the tube 48, thus preventing theadmission of air into the receptacle, and liquid within the receptacle15 can not escape. When the operating member 5.0v is moved into theposition shown in dotted lines in Figure 7, the rod 21 is released andis moved outwardly of the casing and the 4tube 48 is opened to allow theadmission oi airinto the receptacle 15. The lid 39 is now raised and thepiston moved up and down within the cylinder 20. The downward movementof the piston forces air through the tube 29 and the end 31 causing aliquid within the receptacle to pass through the wire strainer 60 andthe tube 36 and' atomizing it through the nozzle 38. During the movementof the piston, the air tube 48 will remain open, as the edge of therecess 51 of the member 50 will abut upon the rod 21, thus maintainingthe plug 54 from Contact with the tube. During the. movement of thepiston air will' be admitted to the upper portion of the chamber 20 andthe device through the opening between the top 22 and the cut-outportion 28 of the casing 10.

When it is desired to dissemble the device, the screw 59 is removed andthe top 22 with its attached parts are withdrawn from the casing.

When it is desired yto remove the receptacle the member 14-17 isremoved.

In the modied form of my device shown in Figure 10, the cover 61 issimilar to the cover 39 previously described, except that the material46 is removed and a hole 62 is made in the cover, thus allowing thedevice to be operated without opening the cover.

Among the valuable properties of my device are the followingz I employ aremovable glass receptacle, thus v overcoming the corrosion incident tometal containers and allowing the use of special design containers; Iemploy a strainer over the liquidv .pipe thus preventing the stoppage ofthe iine exit pipe; I employ a spring above the piston thus overcomingthe diiiculty incident to springs below the piston interfering with thepassageofy air through the exit; when my device is in closed position,the admission of air into the receptacle is prevented thus producing anabsolutely leakless device; my piston is locked within the device whennot in use; a single movement locks the piston and closes the airtube tothe receptacle; a single movement unlocks the piston and opens theairtube to the receptacle; the receptacle can be readily removed andreiilled or replaced without disturbing any of the other elements oi thedevice: the device can be disassembled by the removal of a single screw;the cover can be retained in either open or closed position and numerousother attributes 'which render it of the greatest value.

I do not limit myseif to me particular size;`

shape, number, material or arrangement of parts as shown and describedas these are given simply as a means for clearly describing the deviceoi my invention.
